style="text-indent:25px">磁環(huán)優(yōu)點(diǎn)1、使用非常方便，直接套在需要濾波的電纜上即可；2、不像其它濾波方式那樣需要接地，因此對(duì)結(jié)構(gòu)設(shè)計(jì)、線路板設(shè)計(jì)沒有特殊的要求；3、作為共模扼流圈使用時(shí)，不會(huì)造成信號(hào)失真，這對(duì)于傳輸高頻信號(hào)的導(dǎo)線而言非常可貴。磁環(huán)尺寸確定：鐵氧體磁環(huán)的內(nèi)外徑差越大，軸向越長(zhǎng)，阻抗越大。但內(nèi)徑一定要包緊導(dǎo)線。因此，要獲得大的衰減，在鐵氧體磁環(huán)內(nèi)徑包緊導(dǎo)線的前提下，盡量使用體積較大的磁環(huán)。磁環(huán)應(yīng)用范圍有：電器設(shè)備、音響設(shè)備、醫(yī)療設(shè)備、通訊電源設(shè)備、機(jī)械設(shè)備、儀器設(shè)備、電子設(shè)備以及電源線，數(shù)據(jù)線，信號(hào)線，排線，USB線，音頻線，電纜線，數(shù)碼相機(jī)線，電腦連接線等各種線材與設(shè)備。</p><p style="text-indent:25px">磁環(huán)的原理與實(shí)際作用：鐵氧體磁珠是一種電感器，可以形成被動(dòng)低通濾波器，能衰減高頻的干擾，既可以是設(shè)備本身流出的，也可以是外界進(jìn)入的，而高頻信號(hào)的能量會(huì)被鐵氧體磁芯吸收轉(zhuǎn)換為熱量散發(fā)。磁環(huán)用于鍵盤鼠標(biāo)的USB數(shù)據(jù)線是為了屏蔽沒有用的高頻信號(hào)，因?yàn)閁SB數(shù)據(jù)線通常會(huì)離電腦機(jī)箱很近，如果線材沒有屏蔽層，USB數(shù)據(jù)線就會(huì)像天線一樣吸收周圍環(huán)境或是機(jī)箱內(nèi)硬件所產(chǎn)生的高頻信號(hào)，從而影響到實(shí)際的傳輸。添加磁環(huán)就是一種較為經(jīng)濟(jì)的解決方式。單靠醫(yī)生把脈，是很難得到準(zhǔn)確的病因，所以說醫(yī)療設(shè)備出了干擾信號(hào)。</p><div
